BACKGROUND

Currently, there are application scenarios where a connector is used to connect two electronic devices to perform data transmission between them. In these application scenarios, data transmission consumes a large amount of power. However, since the number of connector ports of the electronic device is usually limited (usually one), it is impossible to supply power to the electronic device by an external power source. When an electronic device runs out of power, a user has to stop using the device and charge it with its connector port. Therefore, the connector of the related art is inconvenient for a user to use electronic devices.

A connector and a second electronic device including the connector of the present disclosure are described in conjunction with the appended drawings.

FIG. 1A is a schematic diagram of a connector, a first electronic device, and a second electronic device according to an embodiment of the present disclosure, in which the connector is applicable to the first electronic device and the second electronic device. FIG. 1B is a schematic diagram of a various circuit connection relationship when the connector shown in FIG. 1A connects the first electronic device to the second electronic device. FIG. 1C is a schematic diagram of another example of a various circuit connection relationship when the connector shown in FIG. 1A connects the first electronic device to the second electronic device. Among them, a connector component is omitted in FIGS. 1B and 1C.

As shown in FIG. 1A, the connector 130 is used to cause the first electronic device 110 to be coupled with the second electronic device 120. The first electronic device 110 can use its own power source to power the second electronic device 120. The second electronic device itself may not have a power source or may have a power source. The first electronic device 110 may be, e.g., a smart phone, a tablet computer, a desktop computer, or other devices. The second electronic device 120 may be, e.g., a wearable virtual reality device, such as Virtual Reality (VR) glasses, a wearable augmented reality device, such as Augmented Reality (AR) glasses, a smart bracelet, a smart phone, a display device, etc. Generally, the first electronic device 110 is the master device and the second electronic device 120 is the slave device, and the master device can communicate data (a video, an audio file, a picture, etc.) to the slave device for various operations of the slave device (such as display operation).

The first electronic device 110 may have a first device-end connector component 111 and a first adaptation circuit (not shown in the drawings) coupled with the first device-end connector component 111. The second electronic device 120 may have a second adaptation circuit (not shown in the drawings). In embodiments of the present disclosure, the adaptation circuit is coupled with the connector component or a corresponding connecting cable. When a connector component of a connector end is coupled with a connector component of a device end, a data line or message transmission line of the connecting cable is coupled with a data transmission port or message transmission port of the adaptation circuit, and signals or data are transmitted through the data line and the message transmission line. The adaptation circuit may also cause a power line of the connector to be coupled with a power source port of the electronic device to supply power to the electronic device. The adaptation circuit can also perform the Power Deliver (PD) protocol. The adaptation circuit may also detect and determine an insertion direction of the connector component, and configure the data transmission port according to the insertion direction. For example, the device-end connector component and the connector-end connector component may be Type-C, Lightning and other types of plugs that can be plugged in front and back, in which cases, the adaptation circuit may configure the data port of the connector socket according to the insertion direction of the connector interface. The adaptation circuit is an adaptation circuit of the corresponding first electronic device and the second electronic device. For example, for a smart phone, its adaptation circuit may be a part of a main control circuit of the phone. For AR/VR circuit, the adaptation circuit may be a part of its internally configured circuit.

As an example, the first electronic device 110 may be a smart phone, and the second electronic device 120 may be VR/AR glasses. When a smart phone is coupled with VR/AR glasses by a connecting cable (such as a USB cable), the smart phone may transfer video, audio file and other data to the VR/AR glasses through a data line of the connecting cable, thereby displaying VR/AR effects on the VR/AR glasses. Meanwhile, if the VR/AR glasses do not have a power source, the smart phone may supply power to the VR/AR glasses through a power line of the connecting cable. Alternatively, even if the AR/AR glasses have a power source, since data display and data processing consume a large amount of power, the first electronic device may also be used to supplying power to the VR/AR glasses. In this case, data transmission using the data display and data processing operations of the second electronic device 120 consume a large amount of power, and when a connecting cable of the related art is used, the power source cannot be used for supplying power. When the power is depleted, usage must be suspended, and the first electronic device 110 and/or the second electronic device 120 must be charged before resuming the usage.

However, with the connector 130 shown in FIG. 1A, power supplying with a power source during data transmission between the first electronic device 110 and the second electronic device 120 can be implemented. The connector 130 includes a data line 131, a message transmission line 132, a first connector component 133, a power-supplying connector component 134, and a power-supplying state detection circuit 135 coupled with the power-supplying connector component 134. The power-supplying connector component 134 is mated with a power source connector component to be coupled with the power source.

The connector 130 also includes a power line (not shown in FIG. 1A). The power line can be coupled with a power source port of the first connector component, a power source port of the second electronic device, and a power source port of the power-supplying connector component, to enable the first connector component and the second electronic device to be coupled with the power-supplying connector component. For example, a power source port of a connector component, a power source port of the second electronic device, and a power source port of the power-supplying connector component can be coupled to the power bus (VBUS).

As shown in FIG. 1B, in an example, the power line may include power lines 136 a, 136 b, and 136 c, coupling the first electronic device 110, the second electronic device 120, and the power-supplying state detection circuit 135 to the VBUS, respectively. The power source port of the power-supplying connector component (not shown in FIG. 1B) may be coupled with a power source port of power-supplying state detection circuit 135, or may be coupled to the VBUS. Therefore, the power line can couple the first electronic device 110 and the second electronic device 120 with the power-supplying connector component. When the power-supplying connector component is coupled with the power source 140, the power source 140 can be coupled with the first electronic device 110 and the second electronic device 120, so that the power source 140 can be used to supply power to both of them.

In another example, the power line may include power lines 136 c, 136 d, and 136 e as shown in FIG. 1C. The power line 136 c couples the power-supplying state detection circuit 135 with the VBUS, the power line 136 d is coupled with the power-supplying state detection circuit 135 and the power source port of the second electronic device 120, and the power line 136 e couples the first electronic device with the power source port of the second electronic device 120. The power source port of the power-supplying connector component (not shown in FIG. 1C) may be coupled with the power source port of power-supplying state detection circuit 135, or may be coupled with the VBUS. Thus, the power line can couple the first electronic device 110 with the power-supplying connector component via the second electronic device 120, so that the power line can couple the first electronic device with the power-supplying connector component via the second electronic device. When the power-supplying connector component is coupled to the power source 140, the power source 140 can be coupled with the first electronic device 110 and the second electronic device 120.

In addition, the power line may also be coupled with the power source port of the power-supplying connector component without via the power-supplying state detection circuit, or may be coupled with the power source port of the power-supplying connector component through the VBUS.

The first electronic device 110 may have a first device-end connector component 111. The first connector component 133 is mated with the first device-end connector component 111 of the first electronic device 110 for coupling with the first electronic device 110. In an example, the first device-end connector component 111 may be a connector port, and the first connector component 133 may be a connector plug mated with the connector port, thus the first connector component 133 can be coupled with the first electronic device 110 when the first connector component 133 is inserted into the first device-end connector component 111.

The data line 131 has a first end which is coupled with a data transmission port of the second electronic device 120, and a second end which is coupled with the data transmission port of the first connector component 133. As shown in FIGS. 1B and 1C, when the first connector component 133 is coupled with the first device-end connector component 111, the first electronic device 110 is communicatively connected to the second electronic device 120 via the data line 131, thereby data can be transmitted between the first electronic device 110 and the second electronic device 120 via the data line 131. Meanwhile, since the power line is coupled with the power source port of the second electronic device and the power source port of the first connector component, the first electronic device may configure its own power source state as a power-supplying state to supply power to the second electronic device via the power line.

The power-supplying connector component 134 may be mated with the power source connector component. In an example, the power source connector component may be a connector plug, and the power-supplying connector component 134 may be a connector port mated with the power source connector component. When the power source connector component is inserted into the power-supplying connector component 134, the power source can be coupled with the third connector component. The power-supplying connector component may be, e.g., a Universal Serial Bus Type-C (USB Type-C) connector plug, a Universal Serial Bus Lighting connector plug, a Universal Serial Bus Type-B (USB Type-B or Micro USB -B) connector plug, a Universal Serial Bus Type-A (USB Type-A or Micro USB-A) connector plug, mini Universal Serial Bus (Mini USB) plug, etc.

The power-supplying state detection circuit 135 is coupled with the power-supplying connector component 134. The power-supplying state detection circuit 135 is configured to detect whether the power-supplying connector component 134 is coupled with the power source. In an example, the power-supplying connector component 134 may be a connector port, and the power source connector component may be a connector plug. In this example, the power-supplying state detection circuit 135 can detect whether the power source connector component is inserted into the power power-supplying connector component 134 in the form of a port, thereby detecting whether the power source is coupled with the power-supplying connector component. The power-supplying state detection circuit 135 may also be configured to obtain power source configuration information of the power source, e.g., parameters such as voltages and currents, etc. The power source configuration information can reflect the power-supplying capability of the power source. The power-supplying state detection circuit 135 may also be configured to detect an insertion direction of the power source connector component, and configure a data transmission port of the power-supplying connector component 134 according to the insertion direction. As shown in FIGS. 1B and 1C, when the power source connector component is coupled with the power-supplying connector component, the power source 140 is coupled with the power-supplying state detection circuit 135.

A first end of the message transmission line 132 is coupled with the power-supplying state detection circuit 135. As shown in FIG. 1A, a second end of the message transmission line 132 may be coupled with the second electronic device 120. Thus, when the power-supplying state detection circuit 135 detects that the power source is coupled with the power-supplying connector component 134 for supplying power, a power source connection message may be transmitted to the second electronic device 120 via the message transmission line 132. In this example, the power source connection message is used to inform the second electronic device 120 that the power-supplying connector component 134 is coupled with the power source.

Upon receiving the power source connection message, the second electronic device 120 may transmit a power-supplying-stop message to the first electronic device 110 to inform the first electronic device to stop supplying power to the second electronic device. Upon receiving the power-supplying-stop message, the first electronic device 110 stops supplying power to the second electronic device. Then, the first electronic device 110 may convert its internal power source state into a power-receiving state to use the power source to supply power to itself. The first electronic device 110 may perform the Power Swap process in the PD protocol to set the power source state as the power-receiving state, so that the power source can supply power to the first electronic device and the second electronic device.

For example, in the case of a smart phone and AR/VR glasses, after the first connector component is coupled with a first device-end connector component of the smart phone, if the power-supplying connector component is not connected to the power source 140, a first adaptation circuit inside the smart phone can cause the smart phone to enter a display data output mode to output a display data to the AR/VR glasses via the data line. Meanwhile, the PD protocol may be performed between the first adaptation circuit and the second adaptation circuit of the AR/VR glasses to make the smart phone to convert the power state to the power-supplying state, so that power can be supplied to the AR/VR glasses via the power line. After the power-supplying connector component is connected to the power source 140, the second adaptation circuit of the AR/VR glasses informs the smart phone to stop supplying power to the AR/VR glasses after receiving the power source connection message.

In another example, the second end of the message transmission line 132 may be coupled with the first connector component 133. In this example, the first connector component 133 may also have a message transmission port in addition to the data transmission port and the power source port, and the message transmission port is used to be coupled with the message transmission line. Thus, when the first connector component 133 is coupled with the first device-end connector component 111, the message transmission line 132 may be coupled to the first electronic device 110. In this example, when the power-supplying state detection circuit 135 detects that the power-supplying connector component 134 is coupled with the power source 140, a power source connection message may be transmitted to the first electronic device 110 via the message transmission line 132. Upon receiving the power source connection message, the first electronic device 110 can stop supplying power to the second electronic device 120. After stopping supplying power to the second electronic device 120, the first electronic device 110 can convert its internal power source state into a power-receiving state to use the power source to supply power to itself.

In an example, the power source connection message may include power source configuration information. The second electronic device 120 may determine whether to transmit a power-supplying-stop message to the first electronic device 110 based on the power source configuration message. When the second electronic device 120 receives the power source configuration information, it may be determined whether the power source has the ability to supply power to the second electronic device according to the power source configuration information. For example, it may be determined whether a voltage, a current, etc. provided by the power source can meet the power requirements of the second electronic device. Then, the second electronic device 120 may transmit a power-supplying-stop message to the first electronic device 110 when the power source has the ability to supply power to the second electronic device, so as to stop the first electronic device from supplying power to the second electronic device. When the second end of the message transmission line is coupled to the first device-end connector component 111, the first electronic device 110 may also determine whether to stop supplying power to the second electronic device 120 based on the power source configuration information, and may also configure the power source state based on the power source configuration information.

After the first electronic device stops supplying power to the second electronic device, since the power source port of the second electronic device is connected to the power source via the power source port of the power-supplying connector component, the second electronic device may receive power from the power source and continue to work. After the first electronic device stops supplying power to the second electronic device and receives power from the power source, the second electronic device can be restarted. After the restart, a data transmission request is again transmitted to the first adaptation circuit of the first electronic device via the data line, so that the first adaptation circuit of the first electronic device configures the data output mode.

Thus, the power source 140 may be used to supply power to the second electronic device during normal data transmission between the first electronic device and the second electronic device, so that endurance of the first electronic device and the second electronic device can be improved.

FIG. 2 is a schematic diagram of a connector, a first electronic device, and a second electronic device according to another embodiment of the present disclosure, in which the connector is applicable to the first electronic device and the second electronic device. In the example shown in FIG. 2, another end of a message transmission line 232 is used to be coupled with a second electronic device 220.

A power line is not shown in FIG. 2, and the power line may couple a power source port of a first connector component 233 and a power source port of a second connector component 236 with a power source port of a power-supplying connector component 234 in any manner. For example, the power line may be respectively coupled with the power source port of the first connector component 233, the power source port of the second connector component 236, and the power source port of the power-supplying connector component 234, to couple the three to a VBUS. The power line may also couple the power source port of the second connector component 236 and the power source port of the power-supplying connector component 234 to the VBUS, and couple the power source port of the second connector component 236 to the power source port of the first connector component 233.

As shown in FIG. 2, the second electronic device 220 has a second device-end connector component 221 and a third device-end connector component 222, and the connector 230 has a second connector component 236 and a third connector component 237. The second connector component 236 and the third connector component 237 are mated with the second device-end connector component 221 and the third device-end connector component 222, respectively. The second connector component 236 is coupled with an end of a data line that is coupled with the second electronic device 220, to couple the data line 231 with the second electronic device 220. The third connector component 237 is coupled with the end of the message transmission line that is coupled with the second electronic device 220, to couple the message transmission line 232 to the second electronic device 220.

When the first connector component 233 is coupled with a first device connector component 211 of the first electronic device, and the second connector component 236 and the third connector component 237 are respectively coupled with the second device-end connector component 221 and the third device-end connector component 222, the connector 230 can enable data transmission between the first electronic device and the second electronic device. When the power source is coupled with the power-supplying connector component 234, the power-supplying state detection circuit 235 may transmit a power source connection message to the second electronic device 220 via the message transmission line 232. Upon receiving the power source connection message, the second electronic device 220 transmits a power-supplying-stop message to the first electronic device 210. After receiving the power-supplying-stop message, the first electronic device 210 stops supplying power to the second electronic device 220, and converts its own power source state to a power-receiving state, so that the power source can supply power to the first electronic device 210 and the second electronic device 220.

In another example, as an alternative to the second connector component 236 and the third connector component 237, the connector 230 may have a fourth connector component. The fourth connector component may have a data transmission port which is coupled with an end of the data line that is coupled with the second electronic device, and a message transmission port which is coupled with an end of the message transmission line that is coupled with the second electronic device. In this example, the second electronic device may have a device-end connector component that is mated with the fourth connector component, and when the fourth connector component is coupled with the device-end connector component, the data line and the message transmission line can be coupled with the second electronic device.

The data line, power line, and message transmission line may be integrated into a connecting cable. The data line and the power line may be integrated into a first connecting cable, and the message transmission line may be integrated in a second connecting cable. In this example, the first connecting cable has a first end which can be provided with a second connector component and a second end which can be provided with a first connector component. The second connecting cable has a first end which can be provided with a third connector component and a second end which can be coupled with the state detection circuit.

The first connecting cable and the second connecting cable may be further integrated in a same one connecting cable to facilitate user usage. The first connector component may be provided at a first end of the same one connecting cable, and the fourth connector component may be provided at a second end of the same one connecting cable.

The connecting cable may be formed as a branched connecting cable, which has a first end which can be coupled with the first connector component, and a second end which can be coupled with the second electronic device or the connector component for being coupled with the second electronic device (e.g., the second connector component, the third connector component, and the fourth connector component). The power-supplying connector component for coupling the power source may be provided at a branch end. In another example, the connector may not be provided with a protruding branch end, e.g., a power-supplying connector component may be provided at intersection of the data line and the message transmission line.

In the example of integrating the power line and the data line into the first connecting cable, the first connecting cable may be any Universal Serial Bus that can implement data transmission function and power transmission function, e.g., may be a Universal Serial Bus Type-C (USB Type-C) cable, a Universal Serial Bus Lighting cable, a Universal Serial Bus Type-B (USB Type-B or Micro USB -B) cable, a Universal Serial Bus Type-A (USB Type-A or Micro USB-A) cable, and a mini Universal Serial Bus (Mini USB) cable, etc.

The first connector component may be a universal serial interface component. For example, the first connector interface may be a Universal Serial Bus Type-C (USB Type-C) connector interface, a Universal Serial Bus Lighting connector interface, a Universal Serial Bus Type-B (USB Type-B or Micro USB -B) connector interface, a Universal Serial Bus Type-A (USB Type-A or Micro USB-A) connector interface, and a mini Universal Serial Bus (Mini USB) interface, etc. In an example, the second connector component and the first connector component may be of the same type.

In an example, the connector of the present disclosure may further include a housing capable of accommodating the first electronic device, the connecting cable may be fixed on the housing, and the second connector component and the third connector component (or the fourth connector component) may extend outward from the housing. At this point, the power-supplying state detection circuit may be arranged within the connecting cable, and may also be arranged within the housing. In this example, the power-supplying connector component may be provided adjacent to a position where the power-supplying state detection circuit is provided. In an example, the first connector component may be provided at a position on the housing that is adjacent to a device end connector of the first electronic device, so as to facilitate the first connector component coupling with the first electronic device when the first electronic device is provided inside the housing. The third connector component may extend outward from the housing, or may be provided on the housing, e.g., may be provided on a side of the housing.

The power-supplying state detection circuit may be arranged adjacent to the first connector component. Since the user may need to hold or move the first electronic device or the second electronic device when using the first electronic device and the second electronic device, by arranging the power-supplying state detection circuit adjacent to the first connector interface, a larger or heavier part of the connector is adjacent to the first electronic device, which facilitates the user moving or holding, and facilitates the user inserting the connector into or pulling the connector out from the first electronic device. In an example, the power-supplying state detection circuit may be arranged within the connecting cable.

In an example, the connector described in embodiments of the present disclosure may act as a component of the second electronic device. FIG. 3 is a schematic diagram of a second electronic device and a first electronic device, which can be coupled with the second electronic device according to an embodiment of the present disclosure.

As shown in FIG. 3, when a connector 330 acts as a component of a second electronic device 320, a power-supplying state detection circuit 335 may be provided in the second electronic device 320, and coupled with a second adaptation circuit 321 of the second electronic device 320 via a message transmission line 332. A power-supplying connector component 334 may be provided on the second electronic device 320, and when a power source is coupled with the power-supplying connector component 334, the power-supplying state detection circuit 335 transmits a power source connection message to the second adaptation circuit 321 via the message transmission line 332. A data line 331 has a first end which can be coupled with the second adaptation circuit 321 and a second end which can be coupled with a first connector component 333. A power line (not shown) may be coupled with a VBUS, and may be coupled with a power source port of a first connector component, a power source port of a second adaptation circuit, and a power source port of a power-supplying connector component. At least a part of the power line and the data line 331 may be integrated into a connecting cable, the first connector component may be provided on an end of the connecting cable. The data line 331 may be coupled with the data transmission port of a first connector component 333, and the power line may be coupled with the power source port of the first connector component. When the first connector component is coupled with the first device-end connector component, the second electronic device is enabled to communicatively connect with the first electronic device via a data line, and the first electronic device is coupled with the power-supplying connector component via a power line.

FIG. 4 is a schematic diagram of circuit connection relationship when a connector according to another embodiment of the present disclosure connects a first electronic device to a second electronic device. In FIG. 4, as an example, a power-supplying state detection circuit 450 is implemented based on a CCG2 chip, and a second adaptation circuit 420 is implemented based on a CCG3 chip. The above-mentioned chips are only listed to illustrate the implementation examples of the connector in detail, and the embodiments of the present disclosure are not limited thereto, and may be implemented by any electronic device capable of implementing the circuit functions of the present disclosure. The power-supplying state detection circuit and the second adaptation circuit may also be implemented based on any electronic device capable of implementing the Power Delivery (PD) protocol and data transmission function. In addition, FIG. 4 only illustrates the connection relationship for explaining the solution of the present disclosure, and other devices or connection relationships are omitted.

As shown in FIG. 4, when a power source connector component (not shown in FIG. 4) is inserted into a power-supplying connector component 440, a power source 430 is connected to the power-supplying connector component 440. A data port of the power-supplying connector component 440 is connected to a CC line of the CCG2 in the power-supplying state detection circuit 450 which is implemented based on the chip, to communicate a power connection message to the CCG2. A I2C data port of the power-supplying state detection circuit 450 is coupled to an I2C data port of a second adaptation circuit 420 via a data line. Thus, the power-supplying state detection circuit 450 can transmit a power source connection message to the second adaptation circuit 420 via a message transmission line.

It should be noted that although the power-supplying state detection circuit and the second adaptation circuit shown in FIG. 4 communicate power source connection messages through I2C communication, those skilled in the art may also communicate the power source connection message through other data communication protocols or formats by rationally configuring the power-supplying state detection circuit and the second adaptation circuit. For example, the power source connection message may also be communicated based on the USB2.0 protocol through rationally configuring the circuits.
